I'm not sure what you're suggesting, but Emacs will always want to allow CLI
input through the GUD buffer which, for example, will be forwarded to GDB as:

-interpreter-exec console "b asdf"

I guess the choices for the query could be presented as a dialog box but I
don't know how that changes things.

Perhap, if as Daiel suggests, after a query GDB will only accept the response
to that query, the old behaviour can be re-instated.
